Description

This PR adds a new chatmode which integrates with the Azure MCP server to assist with Kusto queries. You must install the Azure MCP server.

It can work with any cluster that you have access to but you must explicitly provide the cluster and database name in your query. In the future I'd like to make it save this context to some kind of configuration so you don't have to discover it again each time.

There are a few modes added:

• kusto assistant is a general purpose kusto helper that can answer questions about your data
• kusto table finder can help find the right table for you even when your question is nebulous

I've mainly been testing with GBT 4.1 as I ran out of quota. It can handle simple queries. It should work far better with the more powerful models (it did in previous testing).
